Mucosal healing and control of intestinal mucosal inflammation have been reported as important treatment goals for maintaining clinical remission in ulcerative colitis (UC) and Crohn's disease (CD) patients. In this study, we investigated the availability and efficacy of linked color imaging (LCI), a novel endoscopic enhancement system, for the diagnosis of mucosal inflammation in UC and CD patients. Besides, we investigate the usefulness for prediction of prognosis for UC and CD.

The image enhancement system used in this study is Fujifilm's new endoscopic image enhancement system, which is a signal processing system for images taken in BLI-bright mode of Fujifilm's LASEREO, which irradiates a mixture of narrow-band light and white light (Linked Color Imaging: LCI). In addition, the degree of redness is analyzed by the distribution of pigments in the L*a*b* system, and by quantifying the a* value which is a component of red, we attempt to objectively express the inflammation of mucosal tissue and endoscopic score.
Biopsies from each site taken in LCI mode (four for histological diagnosis, immunostaining, protein analysis, and mRNA expression analysis in the ileum, sigmoid colon, and rectum, and only one for histopathological diagnosis in other sites).
As for protein and mRNA expression in the biopsy tissues, mRNA and protein expression of genes that have been reported to be related to the pathogenesis of IBD (genes related to the pathogenesis of inflammation, proliferation and re-epithelialization of epithelial cells): cytokines, growth factors, short-chain fatty acid receptors, Wnt-related genes, factors related to inflammation and tissue repair such as VEGF, and microRNAs. Protein expression will be examined by Western blotting or ELISA, and mRNA expression will be examined by real time PCR. The above factors will also be confirmed by immunostaining and in situ hybridization to determine the expression cells. Some of the biopsied tissues will be sequenced for RNA expression by Next Generation Sequencing (NGS) to examine the details of RNA expression and the interrelationship of cytokines and other factors. To predict the long-term prognosis, endoscopy will be performed every year from the time of the initial measurement for up to 8 years, and the same study as above will be performed at that time.
